Special Issue Information

Dear Colleagues,

Lignin is the most abundant polyphenol in nature. The pulp, paper, and biofuel industries generate lignin as waste in high amounts. For this reason, the design of novel processes for the valorization of lignin plays a key role in circular economy and green chemistry. Among them, the biodegradation of lignin is an important tool for the transformation of the starting material in order to produce high added fine chemicals, facilities, and commodities. In addition, present-day innovative nanotechnology has increased the chemical potentiality of biodegraded lignin by opening the way for the preparation of nanostructures characterized by improved chemophysical, rheological, and electrochemical properties.

This Special Issue welcomes experimental studies focusing their attention on the following topics:

  • frontiers in the production of added value compounds by microbial degradation of lignin (including biofuel);
  • role of redox enzymes or lignin-degrading auxiliary enzymes for the production of commodities and aromatic compounds;
  • fractionation process of biodegraded lignin and successive nanotechnology and nano-biotechnology applications;
  • application of biodegraded lignin in material sciences and biosensors;
  • application of biodegraded lignin in biocatalysis and biomedical devices.

Original studies and comprehensive reviews on these topics will be accepted for the Special Issue in order to update our knowledge regarding the sustainable applications of biodegraded lignin.

A reliance on fossil fuel has led to the increased emission of greenhouse gases (GHGs). The excessive consumption of raw materials today makes the search for sustainable resources more pressing than ever. Technical lignins are mainly used in low-value applications such as heat and electricity generation. Green enzyme-based modifications of technical lignin have generated a number of functional lignin-based polymers, fillers, coatings, and many other applications and materials. These bio-modified technical lignins often display similar properties in terms of their durability and elasticity as fossil-based materials while also being biodegradable. Therefore, it is possible to replace a wide range of environmentally damaging materials with lignin-based ones. By researching publications from the last 20 years focusing on the latest findings utilizing databases, a comprehensive collection on this topic was crafted. This review summarizes the recent progress made in enzymatically modifying technical lignins utilizing laccases, peroxidases, and lipases. The underlying enzymatic reaction mechanisms and processes are being elucidated and the application possibilities discussed. In addition, the environmental assessment of novel technical lignin-based products as well as the developments, opportunities, and challenges are highlighted. Full article
